That was the night of Dec. 8, when he was partying with the ’Boys. Brent allegedly got drunk and sped away with teammate Jerry Brown riding shotgun. As everybody knows by now, Brent flipped his Mercedes and Brown was killed in the crash.

Brent was back on the sideline Sunday when Dallas played Pittsburgh. The Cowboys say they were just standing by a teammate in need, but it bothered a lot of us. Maybe we’re overly judgmental, but an NFL sideline doesn’t seem like the proper place for guy wearing a booze-detecting ankle bracelet.

They say Brown’s mother asked players to support Brent, to “give your brother love.” If she has no problem with him being on the sideline, why should anyone else?

Perhaps because thousands of viewers have had loved ones killed by drunken drivers. The Cowboys aren’t condoning such behavior, but they also don’t need to stick it in people’s faces to make Brent feel sufficiently loved.

It’s not as if they aren’t supporting him. They placed him on the reserve/non-football illness list, so he’s still collecting his $540,000 salary. A team representative was literally standing by Brent’s side when he made his first court appearance.

From what I’ve heard and read from ex-players, that’s not enough. They don’t think Brent should be embraced all week then shuffled out of public view on Sundays. Their All-for-One mentality demands unconditional support.

Following that logic, why not just give him his starting job back? Or better yet, let him sit in the celebrity seat next to Jones during games. If it’s good enough for Condoleezza Rice and Ashton Kutcher, why not Brent?

The answer is obvious, even though it escapes Brent’s lawyer. There are degrees of support.

If the prosecutors prove their case, Brent deserves compassion and understanding. What he doesn’t deserve is to be treated like the victim.

I’d be more sympathetic, especially since I was occasionally stupid about drinking and driving when I was 24. But look at the facts.

Brent’s blood-alcohol level was 0.18, twice the legal limit. For a 320-pound man to register that, he’d supposedly have to down 20 shots of alcohol in four hours.

Brent knew the risks better than most. In 2009, he pled guilty to DUI in Illinois. And spending 30 days in jail gave him time to reflect.

“You get a new outlook on life and some of the mistakes I’ve made,” he said. “You realize a lot of things, how naïve and dumb you can be sometimes.”

That realization must have left him about the 11th or 12th drink on Dec. 8. He could have used the no-questions-asked car service the NFL provides all players. Now he faces up to 20 years for intoxicated manslaughter.

Here’s one more fact. Brent was reportedly drinking with at least 10 teammates that night at an exclusive club called Privae.

“These fools buying Ace on top of Ace!!!!” the club promoter tweeted.

Ace of Spades is another name for Armand de Brignac. The champagne goes for between $300 and $1,250 a bottle retail. No telling what kind of bill they rang up.

Whatever it was, Brent sure didn’t belong behind the wheel of a car. Now his teammates want him on the sideline to show how much they care.

If only they’d cared enough to stop him that night, he wouldn’t need their help now.
